N'. 1.. a corpora- Application June 18,. 1931. Serial No. 545,202 3Claims. (01- 221-80) This invention relates to a dispensing tube whichis used as an ordinary collapsible tube and which includes an ordinarycollapsible tube which is stiflfened by a coating or an outside tube of5 material stiffer than the metal of the tube. A number of varioussubstances can be used as the coating or outer tubing and it can beapplied by brushing, spraying or dipping. I find that oel-.

luloid is the best material so far used and the dipping the tube in thecelluloid. The tube is preferably coated as soon as it has been made andwhile it is still symmetrical. This coating holds the tube to its shapeduring the subsequent handling when filling and during transportationand selling.

The dispensing 'tube has an improved appearance over the ordinary metaltube because it can be made-all one color when using translucent orsolid color covering or it can give a protective and reflective coveringto a metal tube when the covering is plain or colored transparentmaterial. In case the metal tube is printed upon or is ornamented theouter covering serves to protect the printing.

Another advantage otthis dispensing tube is that by applying a solventto the covering when of celluloid, especially when the covering extendspart way up on the inside or the tube, a per- Iectly tight closing ispossible in the Iolding and sealing of the tube alter filling.

My invention also embraces the method of covering a thin collapsiblemetal tube with a stiflenor in' any other manner.

Atube to illustrate one form of the new article is shown in the drawing.Figure 1 is a view, one .half in section and-one hall in elevation, of atube. Figure 21s a section on line 2--2 in Figurel. a

nozzle 13 having a discharge opening 14. The' nozzle is closed by asuitable cap (not shown) which is usually screwed down over the nozzlewhich is provided with a screw-thread 16 to re-' 'ceive the threads ofthe cap.

ture. Many materials can be used tor this "outer tube but I findcelluloid an excellent material.

A thin outer tube of celluloid resumes its shape after compression andalways presents a neat outside appearance even when the.inner orcollapsible tube has but little material left in it. This is in markedcontrast with the usually partially or nearly'empty collapsible tube asnow made. It is misshapen and any directions or other printed matter onthe. tube is so compressed and wrinkled as to be of no value. In myimproved tube this is not the case. The tube'retains for the most part,a symmetrical form, and when the outer tube is afllxed to the inner tubeit pulls it 1 out into shape after it has been squeezed. The outer tube17' can be made as a separate tube and then placed around the inner tube1 either in. the absence or presence of heat. The usual way is to spraythe material on the collapsible tube 10 into a solution. Qelluloid'after, say, two dippings provides a good outer covering on the innertube. .This dipping is done while the inner tube is new and cylindrical.The outer tube can be carried over the shoulder 12 as at 18 and may alsobe extended over the thread 16 as at 19. I

The lower part i. the outer tube can be extended over for a shortdistance on the inside of the inner tube as at 20. This aids in sealingas the material can be treatedwith a solvent in 35 sufllcient quantityto provide a tight joint and seal when the tube is pressed flat andfolded over after filling. ing, cover byapplying the cover to it bydipping The outer tube can be made as a separate article and thenapplied to the inner tube and in such construction it is held firmly inplace by the fold at the bottom when the tube is closed and by theshoulder part 18 at the top of the tube.

A transparent outer tube either of clearor colored transparent natureor-one made translucent .gives a permanent protection against oxi--dation or dulling of the metal inner tube and also contributes to thetube a pleasingrefiective The article is of a highly ornamentalappearance.

I claim: 4 e

1. A dispensing receptacle comprising a thin non-resilient collapsibletube oi metal and a second tube or celluloid aili'xed to the outside 01the collapsible tube.- the celluloid tube causing the collapsible tubeto resume'itsnormal when squeezing pressure is released, the collapsibletube thus forming. a lining to the resilient celluloid tube. v

or to dip 2. A dispensing receptacle adapted to be collapsed forexpelling contents comprising a tube or celluloid stiff enough to resumeits shape after compression and an inner tube of thin non-resilientmetal, said tubes being secured together whereby the celluloid tubecauses said inner tube. to bedistended in normal condition and said,celluloid tube is shielded from contact withthe'contentsoi the tube. 3.Adispensing receptacle adapted to be cpllapsedtor expellin: contents,comprising a tube portion over the outer surface of which the celluloidtube extends whereby the outer surface of thewhole' article iscontinuous.
